Since the inequality of earnings in East Germany has approached West German levels in the late 1990s, the standard Roy model predicts that a positive selection bias of East-West migrants should disappear. Using a switching regression model and data from the IABemployment sample, we find however...

We use data from a promotion campaign of NH-Hoteles to study self-selection of participants in a gift-exchange experiment. The promotion campaign allowed guests to pay any non negative amount of money for a stay in one of 36 hotels in Belgium and the Netherlands. The data allow us to distinguish...

We examine the earnings determinants of the self-employed and wage earners in Hungary in the mid-1990's, taking into account two forms of selection: selection into working or nonworking for every individual in our sample and selection into self-employment or wageearning jobs for workers only....

Existing research examining the self-selection of immigrants suffers from a lack of information on the immigrants’ labor force activities in the home country, quotas limiting who is allowed to enter the destination country, and non-economic factors such as internal civil strife in the home...

This paper investigates the differences in early occupational earnings of UK male graduates by degree subject during the period 1980-1993. We match administrative student-level data from the Universities' Statistical Record (USR) and occupational earnings information from the New Earnings Survey...

Teamwork and cooperation between workers can be of substantial value to a firm, yet the level of worker cooperation often varies between individual firms. We show that these differences can be the result of labor market competition if workers have heterogeneous preferences and preferences are...

The context of community-based interventions presents formidable problems for any evaluation analysis. Group-randomized studies do possess ideal properties in theory, but in practice, group- randomization might not be a feasible alternative at all or group-randomized studies might be...

With the use of comparable data from seven West African capitals, we attempt to assess the rationale behind development policies targeting high rates of school enrolment through the prism of allocation of labour and returns to skills across the formal and informal sectors. We find that people...

Good teachers are critical for a high-quality educational system. This in turns leads to the question of who is interested in going into the teaching profession. Although research has been done on the professional careers of teachers, the issue of self-selection into teacher education has been...

Several papers have tested the empirical validity of the migration models proposed by Borjas (1987) and Borjas, Bronars, and Trejo (1992). However, to our knowledge, none has been able to disentangle the separate impact of observable and unobservable individual characteristics, and their...
